Minerals may be defined as the combination of two or more elements of a substance.
<u>Five criteria that exhibits a particle to be minerals; </u>
- They are natural and not man-made.
- Inorganic i.e. not made by any organism.
- Minerals are solids, not liquid or gas.
- They have a definite chemical structure.
- The atoms in minerals are arranged systematically and are arranged in a repeated pattern.
Minerals are natural and we use it in our day to day life. Products like salt and even a pencil have minerals. Also, these minerals help the parts in the human body to grow faster and function properly.
Answer:
west to east
Explanation:
The weather system of New York moves in the west to east direction. It is driven by the jet stream which moves from west to east.
The jet stream is nothing but the normal trade winds that blows in and around the equator and move from west to east. While very strong wind forces start blowing from east to west due to the tropical trade winds
Answer:
Ribosomal RNA: Structural part of ribosomes
Messenger RNA: Carry genetic information from DNA to proteins
Transfer RNA (tRNA): Transport amino acids to protein synthesizing complex.
Explanation:
Ribosomes are made up of ribosomal RNA (rRNA) and proteins. The catalytic activity for the formation of peptide bonds between amino acids during protein synthesis resides the RNA of ribosomes.
Messenger RNA (mRNA) is formed by the process of transcription during which the nucleotide sequence of the template DNA strand is copied into that of the RNA. The mRNA serves as a template for protein synthesis. The nucleotide sequence of mRNA is read in the form of genetic codes to specify the amino acid sequence of a protein. In this way, the genetic information stored in DNA is carried to the proteins.
During the process of protein synthesis, tRNAs carry amino acids to the mRNA-ribosome complex so that the amino acids are incorporated into the polypeptide. For the purpose, there is a tRNA with a specific anticodon sequence for a particular amino acid.
b is the right answer because we breathe oxygen and when we breathe out we let out carbon dioxide
